An apparatus for the investigation of low-temperature, high-pressure, vapor—liquid and vapor—liquid—liquid equilibria

摘要: A fluid phase equilibrium apparatus has been designed, built and tested for an operating range of 70 < T 300 K 1 p 200 bar. It consists a high-pressure cell with optical inspection device, gas circulation system, cryostat, instrumentation the measurement or control temperature, pressure composition. Accurate experimental VLE VLLE data are useful as basis either process design testing improvement correlations.
